Created attachment 805210 [details] build.log GCC 11.3.0 fails to build with the mold linker, probably affecting earlier versions as well. GCC 12 works fine. The specific error seems to be "xg++: error: unrecognized command-line option '-fuse-ld=mold'; did you mean '-fuse-ld=gold'?", which happens in the bootstrapping stage.

Created attachment 805213 [details] Build logs produced by GCC
Support for `fuse-ld=mold` was added in gcc 12. https://wiki.gentoo.org/wiki/Mold#Usage
Given that GCC rebuilds itself, and GCC 11 does not support -fuse-ld=mold, the only way to "fix" this would be to ignore your LDFLAGS.
We could backport the patch mentioned on the wiki page, but at this point in the GCC release cycle, it feels a bit pointless and unnecessary risky. There's already too many patches to rebase for 11.x (12.x is a bit better) so I'd prefer not to add more unless really need to.
